Description

Technical Field

[0001] This application relates to the field of egg yolk sorting technology, and in particular to an egg yolk comprehensive detection and sorting machine. Background Technology

[0002] Egg yolks, as a nutritious food ingredient, are widely used in various snack foods. In the egg yolk processing industry, such as salted egg yolks, or artificially produced egg yolks with a harder surface due to the addition of additives, the quality grading and sorting of egg yolks usually rely on manual visual identification. However, manual sorting is not only labor-intensive and inefficient, but the sorting standards are also greatly affected by subjective factors, making it difficult to guarantee the consistency of sorting results and failing to meet the needs of large-scale industrial production.

[0003] With the development of automation technology, some salted egg yolk sorting equipment has appeared on the market. Most of these devices use a weighing principle, that is, measuring the weight of individual yolks with sensors and grading them by weight according to preset weight thresholds, or grading yolks by size using sorting orifices. However, relying solely on physical parameters (such as weight or size) for sorting has significant limitations: weight and size cannot accurately reflect the quality of the yolks. Some yolks may meet the weight or size standards, but their surfaces may have serious defects such as blackening, mold, breakage, or deformities. These problems affecting food safety and quality cannot be identified during the weighing or orifice sorting process.

[0004] Furthermore, while visual inspection devices exist in other food sorting fields to detect the appearance of food, these devices typically transport food in a straight line through the inspection equipment. During transport, the food remains relatively stationary on the conveyor surface. Therefore, the camera can only capture a portion of the food's surface or specific shape features for inspection and sorting, making it impossible to perform comprehensive surface inspection of spherical objects (such as egg yolks). For these reasons, existing sorting methods are insufficient to meet the high standards of food processing enterprises for finished product quality and food safety. Summary of the Invention

[0005] In order to improve the shortcomings of existing egg yolk sorting equipment, which has the disadvantages of incomplete detection and difficulty in meeting the high standards of food processing enterprises for finished product quality and food safety, this application provides an egg yolk comprehensive detection and sorting machine.

[0011] Preferably, a support mounting plate is provided between the two conveying baffles along the conveying direction, and a connecting crossbar is provided on both sides of the support mounting plate and connected to the conveying baffles on both sides respectively.

[0013] Preferably, the air blowing device includes an air blowing mounting plate disposed on the frame along the conveying direction and located above the circulating chain. The air blowing mounting plate has air blowing hole groups on both sides and multiple air supply connectors respectively connected to each air blowing hole group.

[0025] The following is in conjunction with the appendix Figures 1 to 6 This application will be described in further detail.

[0026] This application discloses an egg yolk comprehensive detection and sorting machine, such as... Figure 1-6As shown, the device includes a frame 1, a conveying mechanism 2, several rollers 3, a visual inspection device 4, and a rejection device 5. The conveying mechanism 2 is mounted on the frame 1 and is used for cyclic operation along the conveying direction. Several rollers 3 are rotatably mounted on the conveying mechanism 2 along the conveying direction and are used to carry egg yolks. The visual inspection device 4 is mounted on the frame 1 and located above the conveying mechanism 2. The rejection device 5 is mounted on the frame 1 and located downstream of the visual inspection device 4. The rollers 3 have gears 71 at their ends, and the frame 1 has racks 72 arranged along the conveying direction at positions corresponding to the inspection area of ​​the visual inspection device 4. When the conveying mechanism 2 drives the rollers 3 through the inspection area, the gears 71 and racks 72 mesh to drive the rollers 3 to rotate around their own axes. In operation, the comprehensive egg yolk inspection and sorting machine of this application first transports the salted egg yolks to be inspected onto the conveying mechanism 2 and positions them between two adjacent rollers 3. The arc-shaped surfaces 31 of the two rollers 3 support the salted egg yolks, separating them for transport and inspection, thus preventing them from sticking together and affecting the inspection. Then, the conveying mechanism 2 is activated, and the rollers 3 carrying the egg yolks move in a linear circular motion along the conveying direction. When the rollers 3 and the egg yolks they carry reach the inspection area of ​​the vision inspection device 4, the gear 71 at the end of the roller 3 meshes with the rack 72 at the corresponding position on the frame 1. Since the conveying mechanism 2 continuously drives the roller 3 forward, and the rack 72 is a fixed component stationary relative to the frame 1, the gear 71 is forced to rotate under the meshing action, directly driving the roller 3 to rotate around its own axis. This causes the egg yolks on the surface of the roller 3 to rotate synchronously. During this process, the vision inspection device 4 located above continuously scans or captures images of the constantly rotating egg yolks, completing the acquisition of a 360° image of the egg yolks without blind spots. After processing and judgment, if the image is recognized... If surface defects are found, the rejecting device 5 will remove the defective egg yolks when the roller 3 reaches the downstream rejection device 5. The qualified egg yolks will then be conveyed to the next process. Through the cooperation of the gear 71 and rack 72, this application ingeniously transforms the linear conveying motion of the roller 3 into a rotational motion, effectively eliminating the blind spots in visual inspection during conventional static conveying. This allows for accurate identification of various defects on the egg yolk surface, greatly improving the sorting accuracy. At the same time, this purely mechanical linkage method does not require additional independent motors or control systems, which not only reduces equipment costs and energy consumption but also ensures absolute synchronization between the rotation of the roller 3 and the linear conveying. The structure is simple and the control precision is high. It integrates conveying, rotation detection, and rejection, realizing continuous and efficient automated operation, effectively replacing high-intensity manual labor. Furthermore, the arc-shaped bearing surface 31 of the roller 3 can effectively support the egg yolks. Combined with the stable rotation, it prevents the egg yolks from tumbling and colliding during high-speed conveying and inspection, ensuring the stability of the inspection process. It is particularly suitable for sorting salted egg yolks with fragile and easily broken surfaces.

[0027] Specifically, the conveying mechanism 2 includes a circulating chain 21 and a chain drive assembly 22 that drives the circulating chain 21 to circulate along the conveying direction. Rollers 3 are rotatably mounted on both sides of the circulating chain 21 along the conveying direction. Conveying baffles 23 are also provided on both sides of the circulating chain 21, and the rollers 3 are located between the circulating chain 21 and the conveying baffles 23. The chain, under the action of the drive assembly, circulates and drives the rollers to move. This double-sided arrangement greatly improves conveying efficiency; one machine can occupy one conveyor line to achieve parallel material flow in two rows. At the same time, the baffles effectively constrain the running trajectory of the rollers, preventing them from deviating or shaking during movement.

[0028] More specifically, the outer circumferential surface of the roller 3 has an inwardly concave arc-shaped bearing surface 31. The arc-shaped bearing surfaces 31 of two adjacent rollers 3 jointly bear and position the egg yolk. The egg yolk is placed on the concave area formed by the two adjacent rollers, ensuring that the egg yolk can always be stably positioned between the two rollers when it is driven forward by the rollers and rotates on its own. Each bearing and positioning area is naturally separated by the rollers, which physically prevents adjacent egg yolks from sliding and sticking together. This allows the visual inspection device to take complete and unobstructed pictures and identify the surface of the egg yolk. At the same time, since each egg yolk is independently separated and arranged at a uniform interval, when the visual inspection determines that it is unqualified, the downstream rejection device can accurately target the individual unqualified egg yolk for point blowing or removal. It will not mistakenly reject adjacent qualified products due to egg yolk sticking or uncertain position, creating favorable conditions for subsequent accurate rejection. This effectively overcomes the problem of difficulty in accurate sorting due to egg yolk sliding or rolling aggregation in traditional flat belt conveyors, and significantly improves the accuracy and production efficiency of automated egg yolk sorting.

[0029] Furthermore, there are two circulating chains 21, arranged side by side along the width direction. The chain drive assembly 22 includes a conveying drive motor 221, a conveying shaft 222, a driving sprocket 223, a mounting shaft 224, and a driven sprocket 225. The conveying drive motor 221 is located outside one of the conveying baffles 23. One end of the conveying shaft 222 is connected to the output end of the conveying drive motor 221, and the other end passes through the conveying baffles 23 of the two conveying mechanisms 2. The driving sprockets 223 are arranged side-by-side on the conveying shaft 222 along the width direction; the mounting shaft 224 is arranged along the width direction on the conveying baffles 23 of the two conveying mechanisms 2; the two driven sprockets 225 are arranged side-by-side on the mounting shaft 224 along the width direction; the two circulating chains 21 are respectively wound around the corresponding driving sprockets 223 and driven sprockets 225; the conveying drive motor 221 drives the two driving sprockets 223 to rotate, thereby driving the two circulating chains 21 to run synchronously. A single conveying drive motor drives the conveying shaft, and the driving sprockets arranged side-by-side along the width direction drive the two parallel circulating chains to run synchronously. Its advantage is that the power is split through a shaft that passes through the baffles of the two conveying mechanisms, which reduces the number of drive motors, reduces manufacturing costs and energy consumption, and fundamentally ensures the absolute synchronous transmission of the two parallel circulating chains, that is, ensures that the vision inspection device can synchronously inspect four salted egg yolks located in the same row.

[0030] Furthermore, a support mounting plate 81 is provided between the two conveying baffles 23 along the conveying direction, and connecting crossbars 82 are provided on both sides of the support mounting plate 81 and connected to the conveying baffles 23 on both sides respectively. The support mounting plate 81 corresponds to the upper section of the circulating chain 21. There are two racks 72, which are arranged opposite each other on both sides of the support mounting plate 81 and correspond to the gears 71 at the ends of the rollers 3 on both sides of the circulating chain 21 respectively. When the circulating chain 21 drives the rollers 3 on both sides to pass through the detection area, the two gears 71 mesh with the two racks 72 respectively to drive the rollers 3 to rotate around their own axis. When the upper section of the circulating chain passes through the detection area, the support mounting plate provides support for the circulating chain below the rollers to resist the downward pressure brought by the weight of the material; at the same time, the double racks correspond to the gears at the ends of the rollers on both sides of the circulating chain, ensuring that the rollers on both sides are driven to rotate simultaneously and synchronously by the racks during the straight conveying process, so that each egg yolk can complete a standardized rotation in the detection section.

[0031] Specifically, the rejection device 5 includes a first discharge chute 51, a second discharge chute 52, a third discharge chute 53, and an air blowing device 54. The first discharge chute 51 is located downstream of the visual inspection device 4 and between the two circulating chains 21. The second discharge chute 52 is located on the outside of one of the circulating chains 21. The third discharge chute 53 is located on the outside of the other circulating chain 21. The air blowing device 54 is located on the frame 1, and the two air blowing devices 54 are respectively located above the two circulating chains 21, for blowing the egg yolks on the rollers 3 on both sides of the circulating chains 21 into the corresponding discharge chute.

[0032] More specifically, the air blowing device 54 includes an air blowing mounting plate 541 disposed on the frame 1 along the conveying direction and located above the circulating chain 21. The air blowing mounting plate 541 has air blowing hole groups 542 on both sides. The air blowing mounting plate 541 also has a plurality of air supply connectors 543 respectively communicating with each air blowing hole group 542. One air blowing hole group 542 on both sides of the air blowing mounting plate 541 corresponds to the first discharge trough 51 and the second discharge trough 52 respectively, and is used to blow the unqualified egg yolks on the rollers 3 on both sides of the corresponding circulating chain 21 into the first discharge trough 51 and the second discharge trough 52 respectively. The other air blowing hole group 542 on both sides of the air blowing mounting plate 541 corresponds to the first discharge trough 51 and the third discharge trough 53 respectively, and is used to blow the unqualified egg yolks on the rollers 3 on both sides into the first discharge trough 51 and the third discharge trough 53 respectively. Because the conveying mechanism has two parallel circulating chains, and each chain has rollers on both sides, four parallel rows of egg yolks are formed during actual conveying. The rejection device achieves multi-channel rejection by setting a first discharge chute between the two circulating chains, and setting a second and third discharge chute on the outer sides of the two chains respectively, in conjunction with two sets of air blowing devices located above the chains. The specific working process is as follows: based on the visual judgment result, the air blowing device located above one of the circulating chains blows the defective egg yolks on the rollers on both sides of the chain into the first and second discharge chute respectively through the air blowing hole groups on both sides; while the air blowing device located above the other circulating chain blows the defective egg yolks on the rollers on both sides of the chain into the first and third discharge chute respectively through the air blowing hole groups on both sides. This air path layout only requires two sets of integrated air blowing mounting plates, eliminating the need for complex pipeline switching. It allows defective egg yolks on the four horizontal rollers to fall precisely into the receiving areas on the left outer side (second discharge chute), the two middle columns (shared by the middle two columns, first discharge chute), and the right outer side (third discharge chute). This greatly simplifies the rejection control logic and ensures that the material rejection of the four conveyor channels is non-interfering and clean and efficient under high-speed operation.

[0033] Furthermore, the first, second, and third dropping troughs 51, 52, and 53 are arranged in a straight line along the width direction, and a guide trough 55 is provided below the first, second, and third dropping troughs 51, 52, and 53. One end of the guide trough 55 is connected to the frame 1, and the other end is inclined downwards and passes through the conveying baffles 23 of the two conveying mechanisms 2, used to receive and guide the substandard egg yolks falling through the first, second, and third dropping troughs 51, 52, and 53. During operation, when the vision detection system identifies and controls the blowing device to accurately blow the substandard egg yolks into the first, second, and third dropping troughs arranged in a straight line along the width direction, these three horizontally parallel dropping troughs act as receiving interfaces; since there is a guide trough below the three dropping troughs, with one end connected to the frame and the other end inclined downwards and passing through the conveying baffles on both sides of the conveying mechanism, the substandard egg yolks falling into the dropping troughs will fall onto the guide trough. Relying on the inclined slope of the feed chute and utilizing the material's own gravity, defective egg yolks are smoothly conveyed downwards until they are completely discharged from the equipment. This structural design, combining a horizontal three-chamber collection system with an inclined through-type feed chute, unifies waste materials blown into different discharge chutes into a single discharge channel. This not only effectively prevents the accumulation and retention of defective egg yolks inside the equipment and avoids structural interference caused by multi-channel discharge, but also makes waste collection more concentrated and convenient, ensuring the cleanliness and smooth discharge of the entire sorting machine during long-term continuous operation.

[0034] Furthermore, a cleaning shaft 61 is rotatably mounted on the frame 1 at the front end of the circulating chain 21. Two cleaning brushes 62, each corresponding to one of the two circulating chains 21, are mounted on the cleaning shaft 61. The two cleaning brushes 62 contact the rollers 3 on both sides of the two circulating chains 21. A first cleaning transmission gear 63 is located at the end of the cleaning shaft 61, and a second cleaning transmission gear 64 is located at the end of the conveying shaft 222 that passes through the conveying baffle 23. A transmission belt 65 is mounted on both the first and second cleaning transmission gears 63 and 64. The cleaning brushes are continuously rotated by the power of the conveying equipment, causing frictional contact between the cleaning brushes and the outer surfaces of the rollers on both sides of the circulating chain. This structure enables online automatic cleaning of the conveying rollers without the need for external power, effectively removing residual egg yolk or stains from the roller surface, ensuring the cleanliness of the roller surface during long-term operation, and reducing the frequency and maintenance costs of manual periodic cleaning. As an optional solution of this application, in order to make the roller cleaning more comprehensive, the frame 1 is provided with arc-shaped racks on both sides of the drive sprocket 223. The arc-shaped racks are positioned opposite the cleaning brush 62. The two arc-shaped racks respectively mesh with the end gears 71 of the rollers 3 on both sides of the circulating chain 21. When the circulating chain passes the rollers over the cleaning brush 62, the end gears 71 of the rollers cooperate with the arc-shaped racks to make the rollers rotate, so as to make the rollers more comprehensive.

[0035] Specifically, the visual inspection device 4 includes an inspection mounting box 41 mounted on the frame 1 and located above the conveying mechanism 2, a visual inspection camera 42 housed within the inspection mounting box 41, and a light source 43. The visual inspection device uses the inspection mounting box to enclose the visual inspection camera and light source above the conveying mechanism, forming a closed, light-shielding, and uniformly illuminated inspection environment. Its working principle is that the light source provides stable and uniform illumination, and the visual camera, under ideal lighting conditions shielded from external stray light interference, acquires images of the egg yolk rotating through the inspection area.

[0036] More specifically, the egg yolk comprehensive detection and sorting machine also includes an automatic feeding device 9 and a vibrating hopper device 10. An egg yolk processing sorting device is disclosed in patent application CN108217227A. The automatic feeding device 9 and the vibrating hopper device 10 in this application have the same structure as the automatic feeding device and the vibrating hopper device in the applicant's prior patent application, so they will not be described in detail here.

[0037] The implementation principle of the egg yolk comprehensive detection and sorting machine in this application embodiment is as follows:

[0038] The egg yolk comprehensive inspection and sorting machine of this application uses a single conveyor drive motor 221 to drive two circulating chains 21 synchronously through a conveyor shaft 222 that passes through both side baffles. The power is distributed to four rows of rollers 3 on the left and right sides to ensure synchronous multi-channel conveying. During operation, the salted egg yolks are supported between the arc surfaces 31 of adjacent rollers 3 and move linearly with the chain 21. After entering the inspection area, the fixed rack 72 meshes with the gear 71 at the end of the roller 3, forcing the roller 3 to rotate and causing the egg yolks to tumble continuously. The visual inspection device 4 completes 360° image acquisition without blind spots in a closed light distribution environment, eliminating blind spots. According to the judgment results, the rejection system adopts a three-slot partition and air blowing diversion to accurately blow defective egg yolks into the middle and left and right outer drop troughs 51, 52, and 53, and then discharges them through the lower inclined guide trough 55. At the same time, the conveyor shaft 222 drives the cleaning brush 62 through the transmission belt 65 to continuously clean the surface of the roller 3, realizing online self-cleaning. The machine integrates conveying, flipping detection, rejection and cleaning. It is purely mechanical and requires no additional drive. It is low in cost and has good synchronization, making it particularly suitable for efficient and automated sorting of easily broken salted egg yolks.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application, but should all be covered within the scope of protection of this application.
